The ESP32 S2 WROVER Module works, It connects via USB and i can also program it via there. I did find out that our current 12v power input was not as clean as we thought, but after connecting more capacitors it was fixed. We also tried this on the old chip to see if it was the power supply, but sadl...

We are receiving the esp32 s2 WROVER module tuesday.

Awesome feature that you don't have to use the default uart, didn't though about that. Tested it and worked great!

The ESP32-S2 does have some docs on the GPIO_STRAPPING in the TRM, but bit 1:0 are undefined there. From what I can find if I dig in the archives (it's been 3 years since we worked on that chips design), those bits *may* be defined by the state of U0TX and U0RX (GPIO1/2), but the doc I have isn't t...

Ive been trying to reproduce boo mode and i have to admit i failed. I cant find combination of known bootstrap pins which is giving boot:0xa I can reproduce this message when GPIO46 is high when trying to enter bootloader mode (IO0 + EN): rst:0x10 (RTCWDT_RTC_RST),boot:0x14 (SPI_FLASH_BOOT) ESP-ROM...

Do i need to connect another crystal of 32Khz to the esp maybe? I found one that uses it on an esp32 S2 wroom module, but don't know if this is also for me applicable.

This is my pcb, not sure it helps. After i removed IC4 (the rs485 converter), all communication stopped. Tried to put an 10uF capacitor between gnd and EN, but nothing changed. pcb.png Update Managed to flash a basic print to serial program, i needed to use a 10kohm pullup resitor on the RX line. Sa...

Honestly, I'm kinda scratching my head on that issue... from what you have told and shown here, it should work. Are you sure your PCB matches the schematic, as in, you don't have a short or anything that throws a wrench in the works? Can you try on another PCB? Yeah my pcb matches the schematic exa...

The restart after 3 seconds prints: ESP-ROM:esp32s2-rc4-20191025 Build:Oct 25 2019 rst:0x10 (RTCWDT_RTC_RST),boot:0xa (SPI_FAST_FLASH_BOOT) SPIWP:0xee mode:DIO, clock div:1 load:0x3ffe6100,len:0x524 load:0x4004c000,len:0xa70 load:0x40050000,len:0x292c SHA-256 comparison failed: Calculated: 8dce998ef...

GPIO45 could be an issue if you have it connected to something. According to your schematic you have it NC, though. What would be the best solution? The code is not the problem, sinds a basic blink program does not work and still restarts. On manual restart it happens after 4 seconds and after that...

I tried to upload a simple blink sketch with the arduino ide v2 and v1.8.19 and still resets the esp. Even just trying to use the serial port and to that it will just reboot. Could it be anything with the boot configuration off the IO45 and IO46 pins be that the program keeps crashing? i don't have ...
